Introduction
Recently, Melika et al. (1999) have described a new species from Hungary: Neu-
roterus ambrusi. Dalla Torre & Kieffer (1910) mentioned an Austrian species, Neu-
roterus cerrifloralis Müllner, whose gall is similar to the one produced by N.
ambrusi.
Here in I have studied the type material of Neuroterus cerrifloralis, deposited
in the Naturhistorisches Museum Wien, constituted by 14 entomological needles
with multiple galls in catkins of Q. cerris, and 4 adult specimens (only one per-
fectly conserved). After comparing this material with two paratypes (2 males and
2 females) of N. ambrusi deposited in the author’s collection (transferred by Dr.
Melika in 1999), I have no doubt that both species are the same. Thus, I conclude
that Neuroterus ambrusi Melika, Stone et Csóka, 1999 is a n. syn. of Neuroterus
cerrifloralis Müllner, 1901.
Neuroterus cerrifloralis Müllner is a sexual form well characterized both by
the gall and for the adult morphology (see original description of N. ambrusi in
Melika et al., 1999). The gall is a hypertrophy of the anther. The filament converts
the gall in pedunculated and the anther is partially visible and is joined to the lat-
eral part of the gall (see Fig. 5 of Melika et al., 1999). Adults are characterized by
the following characters: antennae with 14 flagellomeres in females and 15 in males
(F1 longer than F2, strongly curved and distally expanded); scutum and scutellum
glabrous, smooth and transparent; notauli absent; mesopleura finely striated in the
dorsal part; propodeum with no carinae; simple tarsal claws, coxae partially yel-
lowish; femurs yellow in the extremes and brown in the centre.
86 Orsis 22, 2007 J. Pujade-VillarFemales of N. cerrifloralis are morphologically close to N. minutulus Giraud,
1859 and N. aggregatus (Wachtl, 1880); however, N. minutulus has the legs com-
pletely brown and N. aggregatus completely yellow, differing then from N. cer-
rifloralis; moreover, in the case of N. aggregatus, vein R1 is longer than vein 2r,
while in N. cerrifloralis these veins are of equal length; on the other hand, N. min-
utulus is an agamic form.
Males are similar to N. saliens (Kollar, 1857) but the sculpture of the meso-
pleura (finely striated in N. cerrifloralis and finely alutaceous in N. saliens) and
the relative size of the mesoscutum (as long as wide in N. cerrifloralis, longer
than wide in N. saliens) allows differentiating both species.
Galls of N. cerrifloralis are different from any other known gall.
Studied material
Type material of N. cerrifloralis: deposited in the Naturhistorisches Museum Wien,
constituted by 14 entomological needles with multiple galls in catkins of Q. cer-
ris, and 4 adult specimens (only one perfectly preserved). LECTOTYPE (female,
designated herein) with the following labels: “Collect. G. Mayr” (white label),
“Neur. cerrifloralis det. Müllner Type” (handwrited, white label), “cerrifloralis Müll-
ner Typ” (handwrited, white label), “Lectotype Neuroteus cerrifloralis Müllner,
1901 desig. JP-V 2007, det J.P-V 2007” (red label); PARALECTOTYPES: 1male
(deteriored), 2 females (deteriored) and 16 catkins with galls mounted in several
pins (one deposited in JP-V collection) all of them with similar lavels.
Type material examined of N. ambrusi: 2 males and 2 females, deposited in
JP-V collection, with the following labels: “Hungary, Tatabánya, ex catkin gall
on Q. cerris, G. Stone, 12.05.997” (white label), “Paratype Neuroterus ambrusi
Melika desig G. Melika 997” (red label).

ful to my friends Josep Santamaría and Jordi Paretas-Martínez for helping me with
the English spelling and to Jordi Paretas-Martínez for their criticism.
